Panel a: integrated intensity (zero-moment) map of the H2O 55, 0−64, 3ν2 = 1 (232.68670 GHz) molecular line emission. The contours trace emission at the 3, 5, 7, 9, and 11σ levels, where 1σ = 7.13 mJy beam−1 km s−1. Panel b: velocity-weighted integrated intensity (first-moment) map overlaid with the contours of the continuum emission from Fig.1a in grey. The outer extent of the H2O emission matches that of the dust continuum. Panel c: PV diagram for the H2O emission extracted from a 5 pixel wide slice along the dashed line at PA = 25.9° as indicated in (a) and (b). The contours of the data are plotted at the 20–80% levels in steps of 10%, where 10% corresponds to ∼1σ (0.65 mJy beam−1). Panel d: same as (c), but the contours indicate the best representative model using inner and outer disc radii of 30 and 120 au, respectively, a stellar mass of 45 M, and a disc inclination angle of 40°. The spatial (28 mas) and velocity resolution (1.3 km s−1) are indicated by the black cross at the bottom right.
